Inventor: OGOSHI KOJI
IPC: C08L61/20
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor enhancing the quality of a printed image, having high printing resistance and a long service life and excellent in quick optical responsiveness by using specified phenoxy resin and amino resin in a compsn. for an electric charge transferring layer. SOLUTION: This compsn. for an electric charge transferring layer contains phenoxy resin having repeating structural units represented by the formula and amino resin besides an electric charge transferring material such as fluorene or fluorenone. In the formula, (n) is a positive integer showing the degree of polymn. The mol.wt. of the phenoxy resin is 20,000-900,000, preferably 30,000-250,000 as the wt. average mol.wt. (expressed in terms of polystyrene). The amino resin is obtd. by bringing amino stock and formaldehyde into addition reaction and alkyl-etherifying the resultant adduct with 1-4C alcohol. When the amino resin is crosslinked with the phenoxy resin or other amino resin, the hardness of a coating film is increased and the wear resistance is improved.

IPC: H01L21/302
Filed: 1988-03-10
Abstract: PURPOSE:To suppress the yield of coarse parts on the surface due to damage of resist and to flatten an insulating film, by projecting ion beams on the surface of the resist at a specified angle, and performing etching. CONSTITUTION:A wiring 1a that is a protruding part is formed on a substrate 1 on which a semiconductor element is formed. An SiO2 film 2 as an interlayer insulating film is deposited on a substrate 1. Resist 3 is applied on the film 2 and baked. At this time, the surface of the resist 3 is flattened. Ion beams are projected on the surface of the resist 3 at an angle of 15-50 deg.C, and the resist 3 and the film 2 are etched. In this way, the interlayer insulating film can be flattened without the yield of coarse parts on the resist. When the ion beams are projected on the side surface of the protruding part of the insulating film at 15-90 deg.C without using the resist and on the upper surface of the insulating film at an angle less than 10 deg., the protruding part is selectively etched, and the insulating film can be flattened.

At the end of document formation, the character displayed at its size change is displayed in the arithmetically processed state to the changed size. Consequently, input operation with high responseness can be executed while checking the finishing state of a document at the time of document formation. Since it is unnecessary to prepare unnecessary character fonts, excessive storage contents are not applied to the system.
